DRILLING- MACHINE.

SPECIPICATION forming part of Letters Patent No. 344,256, dated June22,1886.

Application filed September 12,1885. Serial No. 176,907. (No model.)

To all whom it may concern:

Be it known that I, DANIEL DULL, a resident of New York, in the countyand State of New York, have invented an Improved Drilling-Machine, ofwhich the following is a full, clear, and exact description, referencebeing made to the accompanying drawings, in which Figure 1 is a frontelevation of my improved drilling-machine. Fig. 2 is a side elevation ofthe same. Fig. 3 is an enlarged central section of the sand-reel whichis used in the machine. Fig. 4 is a face view of that sand-reel. Fig. 5is a central section of the brake-wheel; Fig. 6, aface view of the same;Fig. 7 ,atop View of the pulley over which the rope controlling thedrilling-tools passes; Fig. 8, a side view thereof, and Fig. 9 an endview of the same. Fig. 10 is a horizontal section of the temperscrew onthe line a c in Fig. 2, and Fig. 11 is a horizontal section of the sameon the line k k in Fig. 2.

This invention relates to a new machine for drilling wells, beingapplicable more particularly to the drilling of deep wells.

The object of the invention is, principally, to economize in the cost ofthe machine by compacting the parts as thoroughly as possible; and theinvention consists in the novel combinations of parts hereinafterspecified.

In the drawings, the letter A represents the main framing of thedrilling-machine, in the lower part of which is hung a driving-shaft, B.To the driving-shaft B rotary motion is imparted by a belt from asuitable engine, said belt passing around a driving-wheel, a, which ismounted upon the shaft B.

Fig. 2 indicates by dotted lines the connection between the shaft B andthe driving-en gine.

The wheel a in an ordinary drilling-machine, such as I propose making,should be about seven feet in diameter. The shaft B carries also asand-reel, 0, being a reel intended to hold the sand-pump suspended andto let it down when necessary; also a cam, D, which is intended tooperate the pitman E, that reciprocates the drilling tools. Further, theshaft B carries a drum, F, which is connected with the rope from whichthe drilling-tools are suspended. This drum F has mounted upon it also abrake-wheel, G. The recl Cis loose on the shaft B, but can be throwninto action by a clutch, II In like manner the drum F is loose upon theshaft B, but can be thrown into action by a clutch, I. These clutches IIand I are of ordinary construction and need not here be furtherdescribed. The shaft B at one end is also shown to carry asliding crank,b, which during the rotation of the shaft may be connected with abellows whenever it is desired to use such bellows for the shaping ofthe drilling-tools.

The sand-reel O is more clearly represented in Figs. 3 and 4 of thedrawings, and it is ofa peculiar construction, which I will now proceedto explain.

Upon a hub, d, which surrounds the shaft B, is mounted a peripheralflange, 0. Against the face of this flange are placed two planks, f f,which are both of Wood, of annular form, and placed against one anotherwith their grain crossed. Against the outer side of these planks areplaced the reel-arms g, as clearly shown in Figs. 3 and 4. The outerends of these reel-arms project beyond the peripheries of the planks f,and on their inner faces these arms are notched out down to theperipheries of these planks, all as shown in Fig. 3.

Suitable bolts unite the planks f and arms 9 to one another and to theflange c of the hub 61.

In practice I find that the outer periphery of the reel 0 should beabout four feet, the planksf being each about one inch in thickness,while each reel-arm g is about six inches thick.

The notch or groove around the reel is about ten inches wide and sixinches deep. This gives ample room to wind onto said reel the rope J,from which the sand-pump L is suspended-that is to say, during theoperation of drilling the sand-pump L will be held in the elevatedposition shown in Fig. l by coil ing the rope J upon the reel 0, butfrom time to time, whenever the sand-pump is tobe put in operation, theclutch H is moved to throw the reel 0 into operation, and the sand-pumpis then let down and afterward drawn up again by the reel.

The cam D,which is to reciprocate the d rilling-tools, is surrounded bya strap, '11, which IOC is in two parts, as shown in Fig. 2, both partsbeing bolted together through their projecting parallel arms. The pitmanE is connected to the two-part strap h by plates 73, which are bolted tothe sides of the pitman and pivoted at j to one of the arms that projectfrom said strap. On the pivot j the pitman E is permitted to vibrate inone direction. The upper end of the pitman E is connected by boltedplates Z with a block, m, around which a rope, M, that connects with atemper-screw, N, is placed. This rope M, which in the machine is abouttwo inches in diameter, passes around a pulley, n, that is supported bythe main framework, as hereinafter more fully described. Thetemper-screw N is of the ordinary construction-that is' to say, it isnot of my invention. It serves to connect the rope M with another rope,0, from which the drilling-tools are suspended. One end of the rope O issecured to the drum or bull-wheel F, from which the rope 0 passes arounda friction-pulley, 0, and thence down to the temperscrew N. Thebull-wheel F carries a brakewheel, G, which is surrounded by abrakestrap, 19, that can be worked by a lever, q. When the drillingoperation is going on, the shaft B being revolved reciprocates by meansof the cam D the pitman E. This in turn reciprocates the temper-screwand this raises and lowers alternately that end of the rope O whichcarries the drilling-tools, forcing the latter in the downward strokeagainst the substance to be drilled. As the drilling-tools progress intheirdownward course,the temperscrew is lengthened until its extremeelongation of about six feet is attained, when the temper-screw is againshortened and made to take a new bite on the iron part of the rope O,whereupon operations are continued as before. Whenever necessary, thebrake-lever q is swung down to tighten the strap 19 against the wheel G,and thereby prevents the bullwheel from turning and the rope 0 fromunwinding.

The special construction of the brake-wheel G is shown in Figs. 5 and 6.These figures show that the body of the brake-wheel is composed of threedisks or circular planks, T, which are bolted to the flange or head ofthe bull-wheel F, and which carry near their peiipheries projectingringss s, all of said parts being connected with each other by properbolts. Between the rings 3 a peripheral groove is formed, in which thebrake-strap p is confined. The pulley-wheel n is not hung in the rigidor main frame A directly, but is supported bya hinged platform, P. Thisplatform and its connections, besides being shown in Figs. 1 and 2, ismore clearly represented in Figs. 7, 8, and 9. The platform Pis hingedto the frame A by a hinge, t, which hinge allows the platform to betilted, as in Fig. 8, for purposes hereinafter described. Thehinge t issecured to the frame A by a vertical swiveled pin, u, and thus permitsthe platform P to be moved in a horizontal direction around the pin a.The platform P, when lowered upon the supporting-frame A, as in Figs. 1and 2, connects at its free end with a lever, Q, which is pivoted to theframe Aand engages with a pin on the platform P, so that by swingingthis lever the platform P may be displaced horizontally around the pin.This is done for the purpose of enabling the tools to be drawn out ofthe drill-hole, where but for such horizontal adj ustability of theplatform P the wheel a would be in the way of the tools when they aredrawn vertically out of the drill-hole. The platform P, being hinged tothe frame A, can also be used as a link in a regular pump for pumpingout the drill hole. In this case the rope M and temper-screw aredisconnected from the pitman E,- and the said pitman, or an elongationthereof, is pivoted, as at t in Fig. 8, to the platform P. The saidplatform P, by another pivot, w, or by T-iron, if desired, is} connectedwith the plunger-rodR of the regular pump; hence, when the pitman E isreciprocated up and down the platform P will be swung on its hinge, andwill alternately raise and lower the plunger-rod R, thus pumping out thedrillhole. Whenever this pumping is taking place, the lever Q must ofcourse be discon nected from the platform P, and as a special protectionagainst lateral displacement I put the post :0 through a hole in theplatform P, said post being secured in the framing A, so that on suchpost the platform may be guided, and by it prevented from lateralmotion.

It will be seen that all the parts of this machine can be operated fromthe central shaft, 13, .and that the multiplicity of shafts at presentmade use of in such drilling apparatus is entirely dispensed with. Thusthe mechanism is compacted and rendered less expensive to erect andmaintain, and also less bulky, and therefore more easy to transport.

It will be observed that whenever the pit- ICO IIO

man E is moved up the tool on the rope 0 will be dropped into the well,while when the pitman is moved down said tool will be lifted.

I believe I am the first to unite the pitman and rope M with theseparate actuatingrope O.

I claim- 1. In a drilling-machine, the shaft B, combined with the sandbull-wheel F, clutch. I, cam D, pitman E, rope M, pulley a, rope O, andtemper-screw N, which connects the ropes M and O, substantially as andfor the purpose herein shown and described.

2. The sand reel 0, constructed of the flanged hub d e, planks f, whichare placed against the flange of the hub, and of the radial arms 9 g,which are placed against opposite sides of the planks f and extendbeyond the outer periphery of the same, and which .are notched on theirinner faces down to the periphery of the planks, as set forth.

3. The platform P, carrying the guide wheel a for the actuating-rope M,in combi-. nation-with the hingetand the upright swivman E, plates Z,block m, actuating-rope M, m and temper-screw N, all arranged for operation substantially as herein shown and described.
